Here-strings are not here-documents, so you've been reading the
wrong section of the man page. The section on here-documents makes
it clear that the behavior you've observed is not a bug.
Here Documents
[...]
The format of here-documents is:
[n]<<[-]word
here-document
delimiter
No parameter and variable expansion, command substitution,
arithmetic expansion, or pathname expansion is performed
on 'word'.
